Aregistered nurse is teaching a trainee nurse about the parameters to be assessed in a patient with acute kidney injury who is undergoing dialysis. which statement by the trainee nurse indicates a need for further teaching?
1 "i should auscultate patient's lung sounds."
2 "i should record the patient's input and output."
3 "i should assess for any change in the patient's skin color."
4 "i should examine the patient's mouth for a change in color."

The best answer to the question: Which statement by the trainee nurse indicates a need for further teaching, would be: 4) "I should examine the patient´s mouth for a change in color."

Explanation:

Renal injury, to the point of having to have a patient undergo dialysis is no small matter. This means that the kidneys are absolutely incapable of filtering the blood sufficiently not just to extract waste products that have to excreted, but also to filter out enough water to maintain the balance within the body. Due to the characteristics of this condition, the patient´s body tends to accumulate not just water, but also toxic waste that will cause a series of reactions within the body, and which will become visible on the patient´s different organ systems. However, one thing that will not change will be the color in the patient´s mouth. This might remain the same. However, what can be seen through the mouth is dryness and inflammation. So the nursing student needs to learn that what he/she assesses in the mouth are these two signs, and not color changes.

the answer is d its the most logical and accurate out of them all : )
